Artist JESSICA BARBER speaks with Mosaic of Art host George Fishman about her mixed media work, shown in the "Square Foot Art Basel" exhibition during Art Week in Miami, December 2011. Barber's piece represents an urban train station against the sunset, reddened by the glow of an oil refinery. She talks about "mixing it up," layering oil pastels, acrylic and oil sticks on a clay-coated panel.
